KEGG Database (IMAGE) Neural Regeneration Research Caption Using the KEGG database, we performed signal-net analysis to construct networks of differentially expressed genes. Key genes identified include apoptosis-related, for example Bid and p53 that participate in the P53 signaling pathway, and insulin-like growth factor 1 (Igf1) that is involved in the IGF signaling pathway.
